Description

Technical Field

[0001] The invention relates to the technical field of air compressor cooling, and in particular to an air compressor circulating cooling device and a use method thereof. Background Art

[0002] An air compressor is a device used to compress gas. The structure of an air compressor is similar to that of a water pump. Most air compressors are reciprocating piston type, with rotating blades or rotating screws. They can be divided into several types according to their working principle, lubrication method, performance, etc. The control of air compressor noise mainly adopts three aspects: muffler, muffler tunnel and sound insulation technology. The compressor is directly driven by an electric motor, which causes the crankshaft to rotate, driving the connecting rod to make the piston reciprocate, causing the cylinder volume to change. A large amount of cooling water is required to cool the unit during normal startup of the air compressor. In normal production, the cooling water used for the operation of the air compressor can be selected from Line 1 and Line 2. The switching between them is done manually on site by switching the manual valve. Therefore, once the cooling water system of the party in use fails, personnel are required to go to the site immediately to switch the cooling water. The air compressor will generate a lot of temperature in the process of compressing air. If there is no cooling water, the air compressor unit will stop due to high temperature within two minutes. When the air compressor stops, the pressure of the compressed air drops, causing another normally operating paper machine to stop. Therefore, the safe operation status of the air compressor has a great impact on the paper machine. Summary of the invention

[0013] A method for using an air compressor circulating cooling device comprises the following steps:

[0014] S1. Open the No. 1 solenoid valve on the No. 1 water inlet pipe, turn on the water pump on the No. 1 water inlet pipe, draw the cooling water in the heat exchanger through the No. 1 water inlet pipe and enter the air compressor body to cool the air compressor body. When the water circulates, the water drawn from the No. 1 water inlet pipe enters the No. 1 connecting water pipe after heat exchange, open the No. 4 solenoid valve on the No. 1 connecting water pipe, enter the external threaded cylinder on one side of the No. 1 connecting water pipe, and filter the circulating water through the internally installed filter screen, and then enter one of the No. 2 water pipes through the internal threaded installation cylinder. By manually turning the No. 1 adjusting bolt, the No. 1 adjusting bolt will drive the touch switch to adjust the position. When the water in the No. 2 water pipe enters the water cylinder, it will push the blocking block and the blocking disk to move, and the blocking disk will drive the sealing sleeve to move, and the circulating water will be discharged to the No. 3 water pipe through the water outlet hole;

[0015] S2. When the water pressure is insufficient, the limit block will touch the touch switch, and the water pump on the No. 2 water inlet pipe and the No. 1 solenoid valve will be turned on to perform pressure water replenishment. When the water pump on the No. 1 water inlet pipe fails to work during water inlet, the water pump on the No. 2 water inlet pipe will be automatically started through the control panel to supply cooling water to the air compressor body through the No. 2 water inlet pipe.

[0016] S3. When it is necessary to adjust the pressure of the spring when the plugging disk moves, by turning the No. 2 adjusting bolt inward, the No. 2 adjusting bolt drives the adjusting block to move and presses the spring, so that the pressure that drives the sliding rod to move when the sealing sleeve and the limit block move can be increased, and the detection size of the water outlet pressure can be adjusted;

[0017] S4. When the filter needs to be disassembled and maintained during use, close the No. 4 solenoid valve and the No. 2 solenoid valve, and then open the No. 5 solenoid valve and the No. 3 solenoid valve on the bifurcated pipe, so that the water of the No. 1 connecting water pipe and the No. 2 connecting water pipe can be diverted through the bifurcated pipe, and the limit ring and the filter can be separated and removed by rotating the internal thread installation cylinder, and the filter can be maintained;

[0018] S5. Start the refrigeration water tank through the control panel. The cold water in the refrigeration water tank cools the cooling air duct. Start the fan through the control panel. The fan draws air through the filter duct, cools it through the cooling air duct, and enters the split air box and the outlet air box through the cooling air duct to dissipate heat to the cooling fins on the outside of the air compressor body.

[0019] It is to be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present disclosure.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: by adding a filter net, the filter net can filter impurities from the circulating water entering the external threaded tube, thereby improving the stability of the circulating water; by adding a No. 2 adjusting bolt and an adjusting block, the No. 2 adjusting bolt can adjust the position of the adjusting block when rotating, and the adjusting block compresses the spring, thereby increasing the movement resistance of the limit block and the sliding rod, thereby increasing the movement resistance of the sealing sleeve and the blocking disk, and detecting the circulating water pressure; by adding a cooling air duct, the cold water in the refrigeration water tank can cool the wind passing through the inside of the cooling air duct, and enter the outlet air box through the diverter bellows to be blown out, thereby cooling the heat dissipating fins on the outside of the air compressor body.

Open the No. 1 solenoid valve (8) on the No. 1 water inlet pipe (4), open the water pump (6) on the No. 1 water inlet pipe (4), and draw the cooling water in the heat exchanger (3) through the No. 1 water inlet pipe (4) into the air compressor body (2) to cool the air compressor body (2). During the water circulation, the water drawn from the No. 1 water inlet pipe (4) enters the No. 1 connecting water pipe (35) after heat exchange. Open the No. 4 solenoid valve (36) on the No. 1 connecting water pipe (35), enter the external threaded cylinder (34) on one side of the No. 1 connecting water pipe (35), and pass through the internal installation. The circulating water is filtered through the filter screen (33) and then enters one of the No. 2 water pipes (7) through the internal threaded mounting cylinder (31). The No. 1 adjusting bolt (21) is manually rotated, and the No. 1 adjusting bolt (21) drives the touch switch (24) to adjust the position. When the water in the No. 2 water pipe (7) enters the water cylinder (10), the blocking block (16) and the blocking disk (14) are pushed to move. The blocking disk (14) drives the sealing sleeve (25) to move, and the circulating water is discharged to the No. 3 water pipe (38) through the water outlet hole (15); S2. When the water pressure is insufficient, the limit block (12) will touch the touch switch (24), and the water pump (6) on the No. 2 water inlet pipe (5) and the No. 1 solenoid valve (8) will be turned on to perform pressure water replenishment. When the water pump (6) on the No. 1 water inlet pipe (4) fails to work when water is flowing into the No. 1 water inlet pipe (4), the water pump (6) on the No. 2 water inlet pipe (5) will be automatically started directly through the control panel (46), and the cooling water of the air compressor body (2) will be supplied through the No. 2 water inlet pipe (5); S3. When it is necessary to adjust the pressure of the spring (19) when the sealing disk (14) moves, the second adjusting bolt (23) is turned inward, and the second adjusting bolt (23) drives the adjusting block (22) to move and compress the spring (19), so that the pressure of the sliding rod (13) driven by the sealing sleeve (25) and the limit block (12) to move can be increased, and the detected size of the water outlet pressure can be adjusted; S4. When the filter (33) needs to be disassembled and maintained during use, the No. 4 solenoid valve (36) and the No. 2 solenoid valve (28) are closed, and then the No. 5 solenoid valve (37) and the No. 3 solenoid valve (30) on the bifurcated pipe (29) are opened, so that the water of the No. 1 connecting water pipe (35) and the No. 2 connecting water pipe (47) can be diverted through the bifurcated pipe (29), and the limit ring (32) and the filter (33) can be separated and disassembled by rotating the internal thread installation cylinder (31), and the filter (33) can be maintained; S5. Start the refrigeration water tank (41) through the control panel (46), and the cold water in the refrigeration water tank (41) cools the cooling air duct (42). Start the fan (44) through the control panel (46), and the fan (44) draws air through the filter air tube (45), cools the air through the cooling air duct (42), and enters the split air box (39) and the outlet air box (40) through the cooling air duct (42), and dissipates heat from the heat dissipation fins (43) on the outside of the air compressor body (2).
